[Chimera-users] Can't open the file generated by NORMAD-REF

Dear Mahendra,
The columns are in the wrong place.  Everything from residue number to the right should be moved over one space to the left.

Here is a line from your file followed by a corrected line:

ATOM      1  N   SER B 2010     -15.714 -29.836 129.274  1.00  0.00
ATOM      1  N   SER B2010     -15.714 -29.836 129.274  1.00  0.00

… in other words, chain ID is supposed to be in column 22, residue number is in columns 23-26, etc.  See the "atomic coordinates" section in our Intro to PDB Format:


I attached a corrected file as an example. Maybe you could report this issue to the NORMAD-REF authors.  I hope this helps,

The format of the pdb file looks like ok while trying to follow the former posts like "http://www.cgl.ucsf.edu/pipermail/chimera-users/2012-June/007704.html".
